What this recall means for you

Certain 2017-2020 MAC Trailers dump trailers equipped with Ingersoll Smart-Steer self-steer axles may have a steering arm that detaches from the steering knuckle during certain low-speed, high-side loading maneuvers. Attachment hardware may also fall off and become a road hazard.

A detached steering arm can cause a loss of steering control, and falling hardware can create a road hazard. Both situations can increase the risk of a crash.
